MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains a large number of embedded links pointing to external PDF documents hosted on the domain 'cefasfese.4pu.com'. This behavior is indicative of a link farm or SEO spam campaign, which can sometimes be used to distribute malicious content or drive traffic to malicious sites. No scripts were extracted, and the document body was unreadable, limiting further analysis of the specific lure. The primary technique observed is the creation of a link farm, potentially to obscure malicious activity or for SEO manipulation.

Heuristics 2

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
